P1705 TP SENSOR

Description

INFOID:0000000009719496

The electric throttle control actuator consists of throttle control motor, accelerator pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the ECM, and ECM sends the signal to TCM via CAN
communication.

Vehicle Speed Signal Circuit

• CAN communication with the ABS actua-

tor and the electric unit (control unit) is 
malfunctioning.

• There is a big difference between the ve-

hicle speed signal from the ABS actuator 
and the electric unit (control unit), and the
